您好我正在尝试使用其中一个库中的对象,但我无法通过我的相关上下文。
构造函数是:
public AmbilWarnaDialog(final Context context, int color, OnAmbilWarnaListener listener)
在我的课堂上,我将它用于构造函数:
AmbilWarnaDialog dialog = AmbilWarnaDialog(this, initialColor, new OnAmbilWarnaListener()
{
public void onOk(AmbilWarnaDialog dialog, int[] color) {
// color is the color selected by the user.
}
public void onCancel(AmbilWarnaDialog dialog) {
// cancel was selected by the user
}
});
我收到此错误:
The method AmbilWarnaDialog(Settings, int, new AmbilWarnaDialog.OnAmbilWarnaListener(){}) is undefined for the type Settings
我也尝试过getApplicationContex()和Settings.this,但它无效。
我的进口商品是:
import yuku.ambilwarna.AmbilWarnaDialog;
import yuku.ambilwarna.AmbilWarnaKotak;
import yuku.ambilwarna.AmbilWarnaDialog.OnAmbilWarnaListener;

试试这个:
Context context;
private methodName(Context context) {
this.context = context;
}
在Activity中调用方法:
methodName(this);

你无法直接调用构造函数,实例化一个类使用new
关键字,如下所示:
AmbilWarnaDialog dialog = new AmbilWarnaDialog(this, initialColor, new OnAmbilWarnaListener() { ...
答案 2 :(得分:0)
您正在Settings类中的某处调用此方法(我假设Settings不会扩展Context)。你可能会做这样的事情:
public class MyClass extends Context {
public myMethod(){
new Settings(){
// the keyword this references to the Settings object instance, not MyClass object instance
// to reference Context use MyClass.this
// like Henry says below, make sure you use the new keyword to initialize objects
AmbilWarnaDialog dialog = new AmbilWarnaDialog(MyClass.this, initialColor, new OnAmbilWarnaListener() {...}
}
}
}
